then they told you they wanted to get back together because they still had feelings and had made a huge mistake and still really cared about you and missed you
then they changed their mind because they thought the same problems would happen so you had a big fight because you felt led on by them because they had implied you were getting back together then wanted to just hang out and get with other people and see how it went so it ended really badly in a huge fight.
if a month or so after not talking you messaged them or snapchat, what do you think they would you think?
for example would they be like:
i told you i didn't want to get back together leave me alone you're so annoying
they want to be friends
maybe i can fix this and can try again
